The episode will reportedly deal with the end of New Directions and how Matthew Morrison's Will Schuester will move on. A source also tells THR that several episodes will shift to New York and Lea Michele's character Rachel.

E! News is now reporting Chace Crawford will also appear during the celebration as Dianna Agron's boyfriend. Matthew Morrison told E!'s Marc Malkin, "His name is Biff. He's kind of a Yalie degenerate."

There's sure to be some buzz over who is singing what songs they will perform, but we won't know until we're closer to the episode's release. No matter what, Glee will be going out with a bang.
